Harold’s a pretty hip guy with his own car and a duck tail hairdo.
When he goes to the front door, Mary Sue’s mother answers and invites him in. “Mary Sue’s not ready yet, so why don’t you have a seat?” she says. That’s cool. Mary Sue’s mother asks Harold what they’re planning to do.
Harold replies politely that they will probably just go to the malt shop, or to a drive-in movie.
Mary Sue’s mother responds, “Why don’t you kids go out and screw? I hear all the kids are doing it.”
Naturally this comes as quite a surprise to Harold and he says “Wha…aaat?”
“Yeah,” says Mary Sue’s mother, “We know Mary Sue really likes to screw; why, she’d screw all night if we let her!”
Harold’s eyes light up and he smiles from ear to ear. Immediately, he has revised the plans for the evening. A few minutes later, Mary Sue comes downstairs in her little poodle skirt with her saddle shoes, and announces that she’s ready to go.
Almost breathless with anticipation, Harold escorts his date out the front door while Mom is saying, “Have a good evening kids,” with a small wink for Harold.
About 20 minutes later, a thoroughly dishevelled Mary Sue rushes back into the house, slams the door behind her and screams at her mother:
“Dammit, Mom! The Twist! The Twist! It’s called The Twist!”
